Cocoon->XSP->XSL

["Virdi,T.J." <TV...@cerner.com>]

I am trying to use Cocoon to support distinct user devices as Cocoon
framework is capable to do. Somewhere I am making a mistake and I am not
able to change the XML data by applying XSL stylesheet. I am able to run
example correctly so there is something in my code that is messing things
up. I am calling a FILE1.XML (code to follow) from PDA device. After getting
data from bean, it applies personOut-wml.XSL(Code at the bottom). I would
presume that presentation would change to "Text/wml" but instead I get an
error on PDA device that MIME type "text/plain" not supported. After
debugging, I found data returned to a device (in Hex.) is purely translation
of personOut-wml.XSL in plain text instead of text/wml as I was expecting.
Would someone please tell me what am I doing wrong? Is there something that
I am missing in the code? Your assistance on this is highly appreciated.
Thanks,
TJ

P.S.: I was also wondering if I can dynamically change XSL to a particular
device. For example, in the File1.XML, I have hardcoded personOut-wml.xsl
for media type "wap". Is there any way I can change personOut-wml.xsl as my
default xsl sheet for a wap device and pass personOut2.xsl as a dynamic xsl
sheet to apply for a particular request? Please tell me in anyway I can do
that.
